Hi Jeffrey, thanks for your fast reply. Actually X-Mouse-controls only enable a hidden Windows feature. It's not a program that runs on background. If you see the superuser post, it can also be done by editing registry. Photoshop bring the window to top when activated. All other programs don't. So contacting the developer of X-Mouse-Controls will be of no help. If you still want me to do that, I can do it for you, my friend, but I ensure you that his answer will be: "Contact the developers of Photoshop".
